Answer 2

I got it just by searching for "s-p interval epicenter distance site:.edu"

Answer 3

So u dont even have a guess what the answer is cuz i dont understand this question at all

Answer 4

Actually, now that I look at it again, they gave you an equation they wanted to use. The S-P interval, for this problem, is just a number. The equation they want you to plug it into is,
if n is the s-p interval and x is the distance:
n=0.00146x

Answer 5

Tell me what answer you get and I'll double-check it with mine.

Answer 6

550?

Answer 7

Check to make sure you divided by .00146 and not .0146

Answer 8

Divide that bye what?

Answer 9

Try solving the equation again. If you don't know how, tell me. Double check you type in .00146 (with 2 zeroes)

Answer 10

Ok but what do I divide .00146 by?

Answer 11

You want to find x, the distance to the epicenter, right?

Answer 12

Yes....

Answer 13

Do you know how to isolate x?

Answer 14

No....

Answer 15

That's fine. You want just a equation that is x=the answer. x is multiplied by .00146 right now. So divide both sides by .00146, and you get x!

Answer 16

less than 1 km?

Answer 17

The other side of the equation is n, the s-p interval. So if you divide both sides, you should get:
\frac{n}{.00146}=x

Answer 18

Sorry, \[\frac{ sp.distance }{ .00146 }=x\]

Answer 19

Ok so im right?

Answer 20

You were just off by a zero. Try 8/.00146 in your calculator again, making sure you type in both zeroes.
